DOSE-HANDLING DEVICE.

To all whom 2'2? may concern:

Be it known that I, DANIEL B. STAUFT, a citizen of the United States, residing at Uniontown, in the county of Fayette and scribed in which the crane is mounted upon a frame and wheeled truck or car which is movable along a trackway to permit the crane to be brought into alinement with the oven doors.

further object of the invention is to provide an apparatus of the character described in which provision is made for the convenient adjustment and manipulation of the crane to facilitate and render easy the operations of handling the doors and adjusting the sprinklers.

l Vith these and other objects in View, the invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawings in which Figure 1 is avertical transverse section through the truck and a portion of an oven, and showing the crane disposed in operative position. Fig. 2 is a side elevation on an enlarged scale of the crane per 86. Fig. 3 is a top plan view of the crane. Fig. 4 is a detail cross section on the line 7'-7 of Fig. 2. Fig. 5 is a similar view on the line 8 8 of Fi 2. Fig. 6 is a vertical section through the upper portion of the jack. Fig. 7 is a vertical section through the lower portion of the jack.

In carrying my invention into practice, ll provide a car or truck 1, comprising a truck frame 2 having a suitable floor 3 and provided with supporting wheels to rest and travel upon track rails 5 arranged parallel with the front wall 6 of a series of bee-hive ovens, provided with the doorwaysI-and Specification of Letters Patent.

Serial. No. 43,295.

doors 8, the latter being hingedly and detachably mounted in the usual way. As is well known, doors of ovens of this character are comparatively heavy and difficult to handle, either in opening or closing the same or in removing the doors for repairs or other purposes. in dr: 0* in; the oven at the end of the coking operation, it is first necessary to open the doors and then to cool the inclosed body of coke by subjecting the same to the action of water. It is customary in such cases to open the oven door and then introduce a wintering device by which a spray or streams Patented Jul 42,

of water are directed upon the surface of 'the body of coke to cool the same, such watering devices being commonly handled directly bythe workmen, making the opera.- tion slow, tedious and laborious.

The particular purpose of my invention is to provide an apparatus by means of which. the doors of one or more ovens of a series may be quickly and conveniently opened, closed, removed or replaced in successive order. as occasion may require, through the medium of a crane which is movable from door to door and is adjustable as occasion requires and conveniently operable to enable the door to be handled in an easy manner.

The car 1 supports an upright frame. preferably made like the truck frame. of structural steel, and comprising four corner posts 9 connected and reinforced by sets of crossed braces 9 and carrying, below the upper ends thereof, a horizontal overhead frame 10, also made of structural steel elements. This horizontal overhead frame is composed of parallel longitudinal side bars 11, end bars 12 and intermediate bars 13, tonether with suitable cross braces 14, rendering the frame ofgreat strength and rigidity. The overhead frame may be of any suitable length, and extends in opposite directions beyond the car and the upright frame to approximately equal degrees. Guyrods or wires 15 rest upon or are fastened to the upper ends of the posts 9 and are connected with the outer extremities of the horizontal overhead frame, to further brace and 811s tain the same from the car and central vertical frame. I

Carried by the car is a jack 16, including a bearing sleeve or socket 17, which is adjustable vertically by means of the raising and loweringmechanism of thejack. 'lhe jack may be of any suitable character and i by a shaft 17 shaft is rotatable bearing member 19 suitably mounted upon construction, instance, comprises a fixedhollow base 17*, telescopically engaged by avertically movable sleeve or tubular column 17", a screw.

shaft 17 being inclosed in said base and sleeve and engaginga nut: 17 in the base. At its upper end the shaftcarries a beveled gear l7 meshing with a pinion 17 carried I journaled on the sleeve and provided on the exterior with an actuating crank 17*, whereby the pinion may be operated to rotate the gear and shaft in one direction'or the other, whereby the shaft and sleeve are raised and lowered. The adjustable sleeve or hearing member 17 receives the lower end of a vertical shaft 18 which in said sleeve and in a the top of the vertical frame or central portion of the horizontal overhead frame. The

V 'shaft 18 is threadedfas at 20, for cooperation with the threaded hub of a hand wheel 21, which is vertically adjustable thereon.-

This hand wheel serves asa support and adjusting member for a vertically movable horizontal crane arm or frame 22, having upper and lower guide sleeves 23 and 24: slidablyhand rotatably engagingthe shaft and stably supporting the crane arm, the lower sleeve 24 being secured to the'crane drm by braces or connecting members 25. It will "thus be understood that the crane arm is free to turn or rotate laterally in I either direction or with the shaft 1S, and

. through the medium adjusting device allowing the crane to be shaft through may be raised and lowered by adjustin the the medium of the jac or by adjusting the crane arm on the shaft of hand wheel 21, this disposed at any desired elevation for use.

The main crane arm 225s preferably composed of a pair of channeled beams 22"se cured with their flanges facing each other to form a guideway- 26 and a basals'lot 27 communicating therewith. engagingthis guideway 26' is an extension arm 2? movable on friction rollers .29 and having rack teeth 30'for engagement with for various operations.

the extenslon arm 18. adapted to be PIOJGCtto be raised off its a pinion 31 on a shaft '32 pr.ovi ded With .a crank or the like 33, whereby the said extension arm may be adjusted inwardly and outwardly to vary the length ofthecrane arm. The extension arm carries at its outer end a hook 3,4 of suitable form toengage the handle 35 of; the oven door 8, whereby the crane may be connected ed'so that its hook 34 may slidably engage the door handle, and that the crane may be h raised and lowered, as occasion may require,

for engagement with the handles-of doors at difierent elevations, or to .enable the door base for detachment, or lowered for replacement in position, or disbut, as shown in the presentv 1 .iently drawn or operation; It

Telescopically a crane carried by the mast,

with the door It will be seen that 1,1eo,ose

posed so as to be suspended when not in use either from the crane or some suitable supporting means on the oven wall.

Also it Willbe seen that the crane may be swung laterally on its shaft as an axis to swing the door to open and closed positions, in which operations the extensions arm slides along the guideway'and also'the lever- 35 to con.- i'orm to thearc of movement of the door. By the movement of the apparatus along the track 5 it will be evident that the crane may be brought to a position in line with anyone of the doors for cooperation therewith.

Hinged or pivoted to the outer end of the extension arm, as at 3a, is a pendent head or pressure member 35 movable by means of ahand lever 36, by means of which the door 'hun'g'upon the hook may be supported and gently but firmly pressed to fits seat in the oven opening. I r

In practice, the apparatus maybe con structed and adapted so as to be convenpushed along the track and arranged so that the crane may be employed to open, close,' remove or apply any of the doors, or for successively open ng doors and subsequently closing them prior to the operation of cooling a charge of. coke and later sealing the oven forth'e succeeding coking will be obvious that by means of the improved apparatus these operations may be performed with ease and facility" of labor onthe I and with a minimum amount part of the attendants.

I claim v 1. In a device; for handling co-keoven doors, the combination of a wheeled supporting frame, a post upon the frame, a

' crane arm mounted upon the post for vcrticaladjustment and horizontal swinging motion, said arm being provided with a guida way, an extension arm' movable 'in said guideway, means for vertically adjusting the crane arm, means for moving the extension arm in and out of the guideway, door engaging means on the outer end of the extension. arm, and a swinging door conlower the same, I

a vertically disdoor engaging means ad ustably mounted on said crane arm, an extension arm upon the crane arm provided with a door engaging hook, a presser head pivoted to and hanging pendent from the hook, and a lever for operating said presser head.

4. A device of the character described comprising a wheeled support, a post upon the support, a crane arm pivotally and adjustnbly mounted upon the post, said arm comprising spaced channeled beams form ing a guideway and a slot communicating therewith, an extension arm provided with wheels or rollers and movable in said guideway, said arm being also provided with rack teeth upon the underside thereof, a gear ari'anged within said guide slot and operative for engagement with said rack teeth, a door engaging hook upon the outer end of the extension arm, and a door engaging device pivotally supportedirom said hook.

5. A device of the character described comprising a transportable frame, a mast upon the frame, a crane arm adjustably and pivotally supported by said mast, an extension arm upon said crane arm, means for controlling said extension arm, door engaging means upon the extension arm, and means upon the extension arm for forcing the door to a closed position.

In testimony whereof I afliX my signature in presence of tWo Witnesses.
